Beginner here & also the first time searching for help here

I'm modeling a Sword for a Melee Slasher Game & without an offical SDK(soon), i'm only able to exchange existing Models.

This means i've to keep/use the exact Scales/Dimensions of an existing Sword in the Game, because of the same Hitboxes they've to use etc.

So i converted the UE4 File into .fbx and imported it into Blender Scale/Dimensions are this: Original Scale/Dimensions

Then i build my own Sword in the same Project, to adjust and keep the Dimensions to the Original Sword i'm trying to replace later.

As a Beginner, i once made the mistake and couldnt merge by distance as expected and made my Sword something like 20x times bigger in all directions to merge by distance to get the result i wanted.

Now i cant rescale my Sword-Mesh properly & i'm searching for ages for a solution on the web. This is how it looks, when i'm just typing in the Dimensions of the Original: enter image description here (Unmarked Sword-Mesh=Original / Marked Sword-Mesh=My Model)

(The Dimensions dont fit to my 20x statement anymore, because i already tried many rescalings)

And this is, how it approximately should look like: enter image description here

I dont want to rebuild the whole Sword, even though it could help me to get a better workflow and so on.., but for now i want a solution to this problem, because i could run into this later again. Could somebody give me a Step-by-Step Guide, how to fix that?

Your scale values are locked

enter image description here

Click locks to unlock. Then scale your model to match reference sword. Scale values may not be 1. You can apply scale (Ctrl + a) to make scale values 1.

Or else switch to edit mode, select all vertex and perform the scaling. Doing so won't alter your model scale values

  • $\begingroup$ My Goal is to - have the Mesh visually fitting to the Reference - the Scale is on 1 on xyz - and the Dimensions(Numbers) also fits to the Reference one I already knew the Shortcut and Step 1 & 2 are not that of a problem but Step 3, getting the exact same Dimensions as the Reference one, is the step i cant figure out. (and i think this will be exported aswell, when i'm trying to load it into UE4(?)) $\endgroup$

  • $\begingroup$ So if i just try to do the steps reversed and feed the dimensions input-fields with the correct numbers, my mesh doesnt fit visually. I will now try to do the reversed Way again, and then rescale it in edit mode, maybe this is the way to go. $\endgroup$

  • $\begingroup$ nope, the reversed way doesnt work aswell, the dimensions doesnt fit in object mode again.. gnn $\endgroup$

  • $\begingroup$ Check if there is any isolated vertices away from main geometry $\endgroup$ Nov 7, 2019 at 9:45
